Gents,

I own a 2003 C1500 2WD Extended Cab 5.3L truck with the manual climate control system. My recirculator door motor works but is noisy enough to replace it. I've ordered several parts from different manufacturers and when I plug the actuator in to test it, it simply goes to either full fresh or recirc and stops. It doesn't move. I can plug it into the lower termperature controller and it will work fine. I'm simply not putting in the right part. Does anyone know what the correct part number is? I can show pictures of the original or read the part number right off the old one. I'm pretty sure someone on this forum has run into this. A link to a part would be a GREAT help.

Thanks!

 

When I look it up I see that the Four Seasons Part Number is 73013, and the GM OEM Part Number is 89018678.

Good Luck!
